Abstract:To study the tribological properties of inclined textured surface,a twodimensional calculation model for single microporosity texture was established and the cavitation effect was taken into account.CFD methods were used to simulate the change of cavitation area,textured surface pressure distribution and oil film bearing capacity under different conditions of tilt angle,film thickness and texture depth.The results show that,different from the parallel textured surface,for the inclined textured surface,the oil film bearing capacity of cavitation is not necessarily larger than that of noncavitation,and the oil film bearing capacity is related to the oil film thickness when the tilt angle is fixed.The depth of texture affects the bearing capacity,each calculation model has an optimal depth of texture to maximize the bearing capacity,and the optimal bearing capacity is increased with the increasing of the tilt angle and decreased with the increasing of the oil film thickness.The change trend of the optimal bearing capacity growth rate is closely related to the cavitation.When the cavitation effect is obvious,the optimal bearing capacity growth rate will decrease with the increasing of the tilt angle,and when the cavitation effect is weak,the optimal bearing capacity growth rate will increase with the increasing of the tilt angle.
